      The FAQ page has the install instruction video.
      Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.


      Notice the video does not include SSD cooling required just put it under a heat sink and you are done. Of course that may have no airflow.

      Then all the pictures on the page you quoted not one show it with heatsink or note that this only works with suitable airflow.

      If person does not go down overview that most people don't and click straight on the "TECH SPECS" nothing there warns warns user of the cooling issue.

      FAQ the install video, the "TECH SPECS" the page you pointed to none of them warn about having enough airflow. Motherboard recommendations for airflow over a M.2 slot in most cases if for a PCIe 4.0 M.2 as you said the PCIe 5.0 controller runs hotter so we have a problem.

      Corsairs instructions are not consistent and not where they need to be for the MP700.

      SSD cooling hand waving on to motherboard makers is not good thing.


      Fits directly onto most motherboards

      Scroll down the page where you find that warning and notice the above line. Now you have problem most motherboards instructions are for PCie 4.0 SSD that generate less heat.

      Tech change over points extra instructions to users are required at times.

        One more reason to get 2 or more drives for your data and use at least RAID1 and some checksumming filesystem/volume manager like BTRFS and OpenZFS.
        And yes, every FS will fail to protect your data if you use Intel chipsets and CPUs without ECC RAM and motherboard with ECC support.

          Is it a hardware issue or a driver/software issue?

            This is a hardware issue with poor documentation to warn users of it.

            PCIe 5.0 SSD controllers generate more heat. With out enough airflow/cooling they are either going to have to clock down to the point you might has well be using a PCIe 4.0 SSD instead. Case with this one it did not clock down so it hit the SSD instant stop temperature..

            SSD in general if the NAND chips get to 80C they have to stop. NAND chips hotter than 80C you are going to destroy NAND chips so your data is lost if the tempeture is not brought under control.. Yes a PCIe 4.0/3.0 SSD if you heat the NAND chips to 80+ they will also instant stop dead.

            SSD have strict heat limits.

              In your opinion, will copper ever replaced by optical link connectors?

                Operators of datacenters using PCIe optical signal transmission will enjoy the benefits of lower power consumption and reduced latency.


                Long term maybe short term no. PCie 5.0 over optical is only just being validated. Current day optical tech for PCIe would equal even more heat deal with than using copper.

                Each generation of PCIe over copper has had a shorter and shorter transmission distance before needing signal integrity things this is where the maybe comes in. At some point it may simply not be cost effective to use copper and change to optical to get longer and cheaper transmission range.
